HYDROCARBON-ENGINE.

Application filed July 7. 1914.

To all whom it may concern:

Be it known that I, Oscxn G. Pexouc'rox. a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Hydrocarbon-Engines. of which the following is a specification.

The invention relates to hydrocarbon en gines, and more particularly to the class of combined compressors and engines.

The primary object of the invention is the provision of an engine of this character wherein the'compressor is continuously operated to effect the feed of fuel within the explosive chamber, which fuel when exploded constitutes the motive power for the engine, the exhaust from the engine being utilized as motive power to increase the efii ciency of said engine without utilizing an excessive amount of fuel in the operation of the same.

Another object of the invention is the provision of an engine of this character wherein the explosive chamber will be automatically cleaned for the removal of carbon therefrom during the working of the said engine. v A further object of the invention is the provision of an engine of this character wherein the fluid utilized for the cleaning of the explosive chamber will be primarily admitted to the ackets of the compressor and engine cylinder for the cooling thereof, and subsequently discharged with the exhaust from the engine.

A still further object of the invention is the provision of an engine of this character which will afford maximum efficiency of 'driving power without requiring the consumption of a large amount of operating fluid, and also which will work smoothly without vibration, the engine being of novel form to insure reliability and etficiency in its operation.

A still further object of the invention is the provision of an engine of this character which is simple in'construction. light in weight, yet strong, durable, and also one which is inexpensive in manufacture and installation.

\ Other objects will be in part obvious and in part hereinafter pointed out.

Serial No. 849,606.

The invention accordingly consists in the construction. combination of elements and. arrangement of parts as will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the drawings :Figure 1 is a side elevation of an engine constructed in accord ance with the invention. Fig. 2 is a similar view. looking toward the opposite side of the engine. Fig. 3 is a vertical transverse sectional view on the line 3*?) of Fig. 1.

Fig. 4 is an enlarged fragmentary vertical sectional view through the explosive chamber and valve for controlling the admission of explosive fluid to the engine cylinder and the exhaust therefrom. Fig. 5 is a vertical sectional view through the exhaust rotor. Fig. 6 is a detail side elevation of the valve controlling mechanism.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates a carbureter, B a compressor, C an engine, and D a rotor, which cooperate with each other and constitute the combined compressor and engine, the details of which will be hereinafter fully described.

The engine C comprises a piston cylinder 10 formed with a water jacket 11, and within said cylinder is arranged a reciprocating piston 12, the rod 13 of which extends in opposite directions through stufling boxes 14 provided at opposite sides of the cylinder, while above the said cylinder is arranged the compressor B which is of any ordinary well-known construction, and has its piston connected with the rod 13 of the engine piston 12 so that when the engine is working the c mpressor is active and acted upon directly thereby, the compressor B being mounted upon a support 15 rising from the top of the engine cylinder, while connected with one side of the compressor B is the inlet pipe 16 leading from the carburetor A so that the hydrocarbon fuel will be fed therefrom to the compressor.

At one side of the engine cylinder 10 is formed a valve casing 17 having a two-way turning valve 18 rotatably mounted therein,

while above this valve 18 within the said casing 17 is formed an explosive chamber 19, the latter being adapted for co-imnunica-tion with the engine cylinder 10 through a passage 20 controlled by the valve 18, and formed in the said'casing 1?, the valve being also designed to control the exhaust from the engine cylinder 10 through the passage 2 intersected by said valve and formed in the casing 17, the valve being automatically op erated in amanner presently described.

I Leading from the compressor B to the explosive chamber '19 is a fuel supply pipe 22 in one stretch of which is arranged a cutotf valve rod 23 carrying the valve 2-1 which controls the communication from the pipe 22 to the explosion chamber 19, and this red 23 is acted upon by means of a tension SJI'IIIO 25 which normallv seats the said i l e t valve 24 to close communication between the compressor and the said explosion chamber. Tapped'in one side of the valve casing 17 and projected into the explosion chamber 19 is a spark plug 26, the sparking thereof being controlled in any ordinary Well-known manner; and this plug plode the charges admitted to the explosion chamber 19 from the compressor, which exploded charges are let into the, engine cylinder 10 alternately at opposite sides of the piston 12 for reciprocating the same, the charges to the cylinder 10 being controlled by the valve 18 which automatical y operated in a manner presently describe-o.

Supporting the engine cylinder 10 and valve casing 1'? is a rotor casing or cylinder 27 in which, is arranged a rotor formed in tWo parts suitably joined together and mounted upon a driven shaft 29 journalod in bearings 30 formed centrally of the rotor cylinder 2?, the side Walls ol the latter being provided with exhaust openings 31 concentrically about the bearings 30 for the exhaust of the spent gases from the engine. The rotor is'formecl in its two parts with a spirally arranged exhaust course or passage 32 which increases in area "from its outer to the innermost end thereof, the inner \vider portion of the passage 32 being branched laterally as at 33 to open through opposite sides of the said rotor to permit the exhaust of gas therefrom through the branches 33 and openings 31to the atmosphere. Formed cone centrically about theoutermost convolutions of the spiral way or passage 32 and opening through the periphery of the rotor 28 at the center. thereof are diagonally disposed pockets or exhaust inlets 34 which communicate with the said Way or passage 32 and also communicate with the exhaust passage 21 in the valve casing 17 leading from the cylinder 10 of the engine so that the exhaust fiuid' entering these pockets 34 in the rotor is designed to ex 28 will cause an impact to drive the rotor in one direction. The exhaust fluid passing through the pockets 3i into the passage 32 expands from the periphery of the rotor to the center thereof prior to its discharge through the openings to the atmosphere. so tin thei'uil effect of the exhaust fluid is utilized for iinpelling the rotor 28 to drive the shatt 29. which may be connected to any part or machinery to be driven.

Mounted on the casing or cylinder 27 for the rotor at one side thereof is a cross head guide 35 in which is slidably titted a cross head 36, the same being integral with or connected to the rod 13 ot' the piston 12,, and also pivoted to this cress head 36 is one end of a connecting rod 37 which connected to a crank 38 on the shaft so that power from the engine will be imparted to the said shaft'29 for augmenting the power from the rotor 28, which also drives this shaft.

Arranged upon the base 39 of the rotor casing or cylinder 27. and at one side thereof, is a Water pump e10 its piston stem 41 being pivotally connected to a link 42 eccentrically connected toa gear journaled on one side of the cylinder or casing 2-7, the gear being positioned to mesh with. a pinion all mounted upon the shaft so that motion from. thelatter will be imparted to the pump 40 for operating the same, and from this pump extends a water feed pipe 455 which is tapped into the water jacket of the compressor 13 for thesuppl 'ingof the same with Water during the working of the pump. Mounted in the pipe 45 is therein a three-way valve ii, while leading from this va "e cas' is: is a branch pipe l8, so that on regulanig the valve 47 the Water through the pipe can bedirected into the branch 48, and thus be shut off from flowing into the water jacket of the compressor B. as will be clearly apparent, and in this manner it obviates the necessity of stopping the pump 0 during the continued \\'orl-.';i11g of the eng ne.

Leading from tlu "ter jacket of the compressor B to the water jacket of the engine cylinder 10 is a pipe so that water can be delivered to the jacket of the engine cylinder 10 for the cooling thereof. Rising from the Water jacket of the engine cylinder 10 is a steam exhaust regulator 50. and from the same leads a by-pass pipe 51, the latter opening into the explos on chamber 19 so that when the water conve 15d into steam by the'heat from the engine the same canbe admitted to the explosion chamber 19 for the cleaning thereof to tree it from carbon or other to "gn matter a the stopping of the en pose. Arranged in the pipe 51 is a valve casing 52, the turning valve therein ving connected to an oscillating arm 56 pivoted at 57 to the rotor cylinder or casing 27, the arm 56 being also connected to the pivot 58 on the cross head 36 for connecting the rod 37 therewith, it being seen that on the reciprocation of the head the arm 56 will Swing, and during its movement the valve 53 will be automatically opened and closed for the admission and shutting 05 of steam to and from the explosion chamber 19 of the engine.

Connected to the stem of the valve plug 18 is a toothed sector 59 meshing with a segmental rack arm (30 supported upon a pivot 61 for rocking movement, the pivot being projected from one side of the rotor casing or cylinder 27, and this arm is formed with a fork 62, the,limbs of which are engaged by means of a cam 63 carried by the shaft 29 of the rotor so that on' the latter becoming active the arm 60 actuates the valve 18 for controlling the intake and exhaust to and from the cylinder 10 of the engine.

Tapped in one side of the pump i0 is a supply pipe 64 which feeds water thereto for the pumping of the same into the jackets of the compressor and engine, the heat from the engine being designed to convert the water in the jacket thereof into steam, which is conveyed into the explosion chamber 19 for scavening the same to free it of carbon or other foreign matter, the converted steam being controlled through the regulator 50 so that an excessive amount of steam can be exhausted to the atmosphere while the engine is active.

It will be noted that the exhaust from the engine is utilized for driving the rotor so that the power therefrom willv augment the power from the engine for driving energy to be utilized in operating machinery or other purposes.

It will be apparent that the operation of the device is continuous and without any lost motion, and at the same time enabling maximum power to be attained with a minimum consumption of fuel.

From the foregoing descriptioh, taken in connection with the accompanying drawings, it is thought that the construction and manner of operation of the device will be clearly apparent, and therefore a more extended explanation has been omitted.
